CARBURETER FOR HYDROQARBON-ENGINES.

No. 806,079. A

To all whom 2325 may concern.-

Be it known that I, OSCAR GAVELEK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois have invented certain new and useful vImprovements in Carburete-rs for Hydrocarbon- Engines; and'I do hereby declare the followingto be a full, clear,.and exact description of the invention, such as willenableothers skilled in the arthto which it appertains to make and use the same.

My invention relates to a novel construction in a carbureter particularly adapted for use in connection with gasolene-rnotors, the'object being to provide a device in which the feed of gasolene or other vapor and air are simultaneously controlled by a single lever, which determines the proportions of each admitted to the motor tocontrol the speed and power of the latter; and itconsists in the features of construction andcombinations of parts hereinafter fully described and claimed,

1n the accompanying drawings, illustrating my invention, Figure 1 is a central vertical section of acarbureter constructed in accordance with 'my invention. Fig. 2 is a detail .view in 'elevationof the throttle-valve employed.

I I My said device comprises a' casing themiddle portion of which constitutes a verticallydisposed cylinder A, connected at its lower end with an air-inlet B and connected at its upper end with the suction end of the motorcylinder by means of the pipe C. .The upper end of said cylinder A is externally threaded to receive a flanged nut or collar D, by means of which the cylindrical throttle-valve E, mounted in the upper end of said'cylinder, is held in place; The said throttle-valveE is open at its lower end and is provided between its endswith a substantially triangular opening F, through which communication is established between said cylinder A and pipe C, the said triangular opening F determining the volume oi'carbureted air admitted to said pipe G, and thus to the motor-cylinder at each stroke of the piston in the latter. Disposed vertically in the middle of said cylinder A at its lower end is a valve-casing (Jr, having an inlet H at one side, which" isconnected with a source of supply of gasolcne or other volatile hydrocarbon. liquid or gas by means of the pipe J and having an outlet-passage K, which Specification of Letters'Patent; Application filed July 25', 1904.

L, entering said casing G at its lower end, mid which is further controlled by a pinwalve M, seating on a valve-seat at the, upper end of said passage K. The said valve M carries a horizontally-disposed disk'N between its ends, which is of less diameter than the casingA or throttle-valve E and isdisposed belo'w the At its upper end said valve M carries a stem 0, which is longitudinally movable in a central longitudinal opening P in avert-ically-disposed plunger R, the latter being threaded between its ends and passing through a central threaded opening in the -upper wall of the throttlevalve E and a similar opening in the end of an operating-lever Syrigidly secured to said throttle-valve. At its upper end said plunger R carries a vertically-adjustable collar T,

. in position on the said plunger by means of opened by the pressure of carbui eted air on the lower face of said disk N at each, stroke of the piston of the motor, the extent of opening of said valve being determined by the piston of said plunger R. The said throttlef valve E is so arranged that when it is desired to admit carbureted air to the motor the smaller end of the opening F first establishes communication between the cylinder A and -pipe G, and as said valve is turned farther a larger opening is gradually provided. When the throttle-valve is entirely closed, the said plunger R is lowered, so as to bear on the .upper end of the said valve M to hold same positively closed independently of valve L, which may remain open. As the throttlevalve is opened the said plunger R is'gradually raised, thereby gradually allowing the valve M to open wider and admitting a quantity of hydrocarbon liquid propoiftioned to the volume of air which can pass through the o enim F such liquid being immiel a a diately evaporated, and thus-carbureting the air. The motor is thus controlled by a single lever, and the valve E may be connected with the governor of the motor and the latter be is controlled at its lower end by the pin-valve thus partly controlled automatically. 7

A-light My said devicejs very simple, cheap, and efiicient.

I claim as my invention- Acarbureter forhydrocarbon-motors, comprising a cylindrical casing provided at one end with inlets for air and hydrocarbon liquid respectively, and at its other end with an outlet for carbureted air,'a throttle-valve controlling said outlet, a valve controlling said inlet for liquid,'fiuid-pressure-actuated means on said last-named valve for opening same, a longitudinally-movable plunger disposed in the path of said valve and controlling the degree of opening movement of same, said plunger being threaded between its ends and passingthrough a threaded opening in said throttle-valve, means for holding said plunger against revolution, and means for holding said throttle-valve against longitudinal movement, whereby when said throttle-valve is turlfied said plunger will be moved longitudina In testimony whereof I have signed. my name in presence of two subscribing witnesses.
